Question
Code must use multiple "methods" and output must match the example. Thank you! Problem 4-Volume and Weight Converter [30 points Write a program called Volume and Weight Converter (VolumeWeightConverter java) that will perform the following conversions Gallon to Liter . .Liter to Gallon Pound to Kilogram Kilogram to Pound . . In your main method, display a menu with each of these choices plus an additional choice to exit. P option, then call the corresponding methgd to prompt for a value and display the converted result. user for a menu Your resulting program should have five methods: main and one method for each of the conversion functions. The calculation must be performed in those four methods, and the result should be printed from the main method. After the converted value is displayed, display the menu again and repeat until the user chooses the Exit option. Hints: Your menu and the calls to the other methods must be inside a loop. Use double values, not int values. format the output. Use printf to Create the following four methods in addition to your main method: Method gallons ToLiters gallons 3.785 liters ToGallons liters 0.264 pounds ToKilograms pounds.0.454 kilograms ToPounds kilograms 2.205 CalculationExplanation / Answer
